Method of integrating functional tuning materials with micro devices and structures thereof

Abstract

The disclosure is related to creating different functional micro devices by integrating functional tuning materials and creating an encapsulation capsule to protect these materials. Various embodiments of the present disclosure also related to improve light extraction efficiencies of micro devices by mounting micro devices at a proximity of a corner of a pixel active area and arranging QD films with optical layers in a micro device structure.

I claim: 
     
       1. A method to improve light extraction efficiencies, the method comprising:
 providing a plurality of pixel structures, each pixel structure of the plurality of pixel structures having at least three subpixels; and 
 providing color conversion films over the plurality of pixel structures to convert light of one or more of the at least three subpixels for each pixel structure of the plurality of pixel structures, 
 wherein a first of the at least three subpixels has stacked first color conversion layer and second color conversion layer, a second of the at least three subpixels has one of the first color conversion layer or the second color conversion layer, and the third of the at least three subpixels has none of the first color conversion layer or the second color conversion layer. 
 
     
     
       2. The method of  claim 1 , wherein the third of the at least three subpixels has no conversion layer for saving power. 
     
     
       3. The method of  claim 1 , wherein the third of the at least three subpixels generates blue color only.
